We've been paddling for about 10 years or so. Pretty casual - mostly costal and big lakes. We've been out of plum island and Ipswich and really love to go out in Casco Bay, Maine in and around the Bath area. We've paddled with a couple friends from time to time, but not in a group. We are looking new places to go and are looking forward to meeting new people too.Waves are great, but we're a little wary of rocks and rough seas. Since we've never done this paddle before, how long of a trip to you estimate?
